Hi there,
pass mark =185+15=200
let x be the total mark
then  40/100*x=200
40x=20000
x=20000/40=500
therefore the total mark =500
i hope this helps u

\mathfrak{\large{\underline{\underline{Answer :}}}}

The total marks are 500.

\mathfrak{\large{\underline{\underline{Step-by-step\: explanation}}}}

\textsf{\underline{\underline{Given : }}}

Students needs = 40% to pass

Rula gets = 185 marks

Fails by = 15 marks

\textsf{\underline{\underline{To find :}}}

The total marks

\textsf{\underline{\underline{Solution : }}}

\textsf{Let the Total Marks be as x }

As Rula failed by 15, the marks she scored when added by 15 makes the passing marks.

\green{\boxed{\green{\boxed{\red{\sf{40\% \: of \: x = 185 + 15}}}}}}

\begin{lgathered}\begin{lgathered}\sf{\longrightarrow} \: 40\% \: of \: x = 185 + 15 \\ \\ \sf{\longrightarrow} \: \frac{40}{100} \times x = 185 + 15 \\ \\ \sf{\longrightarrow} \: \frac{40x}{100} = 200 \\ \\ \sf{\longrightarrow} \:40x = 200 \times 100 \\ \\ \sf{\longrightarrow} \:40x = 20000 \\ \\ \sf{\longrightarrow} \:x = \frac{20000}{40} \\ \\ \sf{\longrightarrow} \:x = 500\end{lgathered}\end{lgathered}

\textsf{Total Marks = 500 }

\therefore\textsf{The total marks are 500. }
